I/O's information columns in the system monitor

I/O's information columns in the system monitor.
I think it would be useful knowing the IO's behaviour (read, write, delta w, delta r, etc) of each task in my computer by the system monitor.

Solution #1: Auto-generated solution of idea #3311
Written by yzarc the 5 Mar 08 at 11:24.
Ubuntu Brainstorm was updated in January 2009. Since the idea #3311 was submitted before this update, its rationale and solution are not separated. Please vote accordingly, and if you have the necessary rights, please separate the rationale from the solution. Thanks!

Solution #2: Let top display 'wa' also per process.
Written by Cé the 26 Feb 09 at 19:36.
Top has the field 'wa' showing the time processes have to wait for disk IO. When this number is high, the computer is slow. It's however not possible to see what process is using the disk.

It would be nice if top shows for each process the 'wa' field.

Solution #3: iotop
Written by EmheMah the 21 Sep 09 at 13:08.
Taken from http://www.debianadmin.com/iotop-simple-top-like-io-monitor.html

apt-get install iotop

iotop needs the CONFIG_TASK_DELAY_ACCT and CONFIG_TASK_IO_ACCOUNTING options enabled in the kernel; in Debian stock kernels, that’s already the case.

Worked for me with Jaunty
